remember, 4.5 billion is what we spend for a day to operate in that environment. saving two when you are -- will not go on the street with the exception of package delivery, which will be done with dynamic routing, with a lower cost employee, whether in the rural or city craft, allows us to provide that kind of service as a lower cost. the mail costs, the transportation costs, network changes, that's all money that can come out of the system. we've also calculated in what we think is the revenue loss and we've talked to a lot of customers to validate that. so the 2 billion is doable. people say well, it's only two out of 20 billion. it is not. if we had it this year we would break even from an operational standpoint. this year we'll lose ago 1.7 billion in the operating line. that's revenue minus costs with the exception of workers' comp costs and prefunding. we would make money if we had made the six to five move at the beginning of this year. that gap exists when you do nothing over a five, six, four or five-year period and with inflation that continues to grow.
